-# VMs monitoring
-SkyWalking leverages Prometheus node-exporter for collecting metrics data from the VMs, and leverages OpenTelemetry Collector to transfer the metrics to
-[OpenTelemetry receiver](backend-receivers.md#opentelemetry-receiver) and into the [Meter System](./../../concepts-and-designs/meter.md).
-We define the VM entity as a `Service` in OAP, and use `vm::` as a prefix to identify it.
-
-## Data flow
-1. The Prometheus node-exporter collects metrics data from the VMs.
-2. The OpenTelemetry Collector fetches metrics from the node-exporter via Prometheus Receiver and pushes metrics to SkyWalking OAP Server via the OpenCensus gRPC Exporter.
-3. The SkyWalking OAP Server parses the expression with [MAL](../../concepts-and-designs/mal.md) to filter/calculate/aggregate and store the results.
-
-## Setup
-1. Setup [Prometheus node-exporter](https://prometheus.io/docs/guides/node-exporter/).
-2. Setup [OpenTelemetry Collector ](https://opentelemetry.io/docs/collector/). This is an example for OpenTelemetry Collector configuration [otel-collector-config.yaml](../../../../test/e2e/e2e-test/docker/promOtelVM/otel-collector-config.yaml).
-3. Config SkyWalking [OpenTelemetry receiver](backend-receivers.md#opentelemetry-receiver).

# K8s monitoring
SkyWalking leverages K8s kube-state-metrics and cAdvisor for collecting metrics data from K8s, and leverages OpenTelemetry Collector to transfer the metrics to
[OpenTelemetry receiver](backend-receivers.md#opentelemetry-receiver) and into the [Meter System](./../../concepts-and-designs/meter.md). This feature requires authorizing the OAP Server to access K8s's `API Server`.
